All the times I've personally witness this problem it was dues to:
A: grounding LFRAME instead of soldering it to d0 on the chip
B: An eeprom "issue" (If the xenium OS recognizes your eeprom to be from an xbox version that isn't the version you have... solution here is to reflash your eeprom until it correctly recognizes the version...)
There are possibly other factors leading to this as well, such as a shot onboard BIOS... In any case, if you can't resolve your issue, you can always download a copy of the correct retail bios for your xbox and flash it to the chip it self (1.6 is 5838). Then you can play live just fine
